In Great Britain July .13, 1934 during the sewing operation. This method of attaching the tapes has certain disadvantages,

namely, the attachment is usually so loose that 15 the tapes require to be subjected to an additional handor machine-operation of pasting their ends to the sides of the books in order to make them secure from displacement during the subsequent bookbinding operations. Subsequent to the past ing down of the tapes the backs of the books are coated with glue to'ensure adhesion between the signatures of the book and as the glue cannot be fully worked in below that area of the backs of the books which is covered by the tapes the full 25 strength of the book back is thus unattainable by this method.

Further, the top surfaces of the tapes are saturated with this glue and they may dry in a wrinkled condition and dry very hard before the 30 rounding and backing operations are performed and thus render such operations much more diffioult and destructive to the tapes.

The aforesaid disadvantages can be avoided by delivering the tapes from spools to the glued 85 backs of the books subsequent to the rounding and backing operations and simultaneously with the application of the scrim or crash or first lining.

My invention resides in an improved arrangement by which reels of much greater length than 40 the width of the tapes and consequently containing large quantities of tapes can be used and the tapes delivered to the scrim at a constant position in relation to the book despite the fact that the tapes will be delivered from constantly chang- 45 ing portions of the reels.

prior PatentNo. 982,438 which are necessary for grammatically an arrangement in accordance with the invention for feeding the tapes simultaneously with the scrim or crash to the already glued backs of books, the means (not shown) for applying the scrim to the backs of the books be- 5 ing assumed to be similar for instance to that shownin Figs. 8 and 9 of my said prior patent and servingalso to apply the tapes to the backs of the books in the same operation. Fig. 1 is a front elevation, Fig. 2a plan view and Fig. 3 an 10 end elevation of an-arrangement of the feeding mechanism suitable for feeding four spaced tapes from reels of greater length than the width of the tapes, and containing'a large quantity of tape, to the backs of books simultaneously with the scrim.-'-. -Fig. 4 is a detail to enlarged scale of the tape guiding mechanism shown in Figs. 1 to 3, and Fig; 5 isza-pla'n View of Fig. 4.

. Throughout the several figures of the drawings only those parts of the machine disclosed in my an understanding of" the present'invention are shown and described.

In the drawings, I denotes the table of the machine, 2 the scrim or crash roll from which the scrim or crash is led over the guide or tension rods 3, 3' to the scrim feed rolls 4, 4' whence it is passed over the glued backs of the books such as 5, is severed, and applied thereto say as described in my said prior patent. In my invention tapes are fed to the backs of the books and applied thereto simultaneously with the scrim or crash and subsequent to the rounding and backing operations on the books if such operations are carried out. To this end'there are associated with the scrim roll, tape reels from which tapes are fed to the backs of the books at the same time as and by the same feed rolls 4, 4 as those feeding the scrim or crash and are severed and applied to the books simultaneously with the latter. 40

In the arrangement shown, which, as stated, is adapted for use with reels containing large quantities of tape wound on reels of much greater length than that of the tape and therefore delivered from constantly changing portions of the reels, auxiliary guide means is provided for ensuring that the tapes thus led from the reels will pass under the scrim at a constant position in relation to the book. In the particular form shown four sets of tapes l0 are supplied with the scrim.

As shown, the table I is fitted with two reel supporting frames each denoted generally by the reference numeral I2, and each consisting of a bracket l3 bolted to the table and provided with a pair of reel supporting spindles l4 in superposed parallel relation and pairs of guide rods 1, I, the reels l being disposed in planes at right angles to the plane containing the axis of the scrim feed rollers 4, 4. In order to permit easy removal and replacement of the tape reels l0 they are held on the spindles I4 by means of pivoted arms l5 formed with hook slots I6 adapted to engage reduced portions of the reel spindles I4. One of said arms I5 is shown in Fig. 1 both in full lines in locking position and in dotted lines in a raised position permitting lateral withdrawal of the reel from its spindle.

In order to ensure satisfactory feed of the tapes ID from the point from which they leave the reels and in which they extend at right angles to the scrim, into a position in which they move parallel with the scrim, there are mounted on bearing brackets 6 secured to the table I and beneath the scrim roll 2 superposed guide rods l8, l8 from which the tapes pass upwards to the scrim feed rolls 4, 4 and on these guide rods l8, l8 are carried spaced bracket arms l9, I9, 20, 20, on the ends of each of which are mounted guide rollers 2! with vertical axes at such heights as to ensure a quarter turn of the separate tapes as they pass to the guide rollers 2| and to ensure a further quarter turn as they pass around the guide rods I8, l8 to the feed rolls 4, 4' for the scrim.

The arms l9, I9, 20, 20 may be displaced on the rods I8, I8 as desired and clamped in any desired position by means of the split clamp shown in Figs. 4 and5 in order to provide any desired spacing of the tapes.

The tapes are guided from the reels over the rollers 2| to the guide rods [8, l8 and. thence to the feed rolls 4, 4' passing between them under the scrim so that when they are severed into lengths and applied to the backs of books such as that 5 shown the tapes will lie between the back of the book and the scrim.

I claim:

1. In a bookbinding machine in combination with scrim rolls and feed rolls for feeding the scrim to the back of the books, means for delivering a plurality of relatively narrow tapes with the scrim to the feed rolls and to the back of the books in a constant position in relation to the width of the scrim from a plurality of relatively wide tape reels affording supplies of tape, said means including a plurality of tape reels in spaced relation, said reels disposed with their axes at right angles to the axis of the scrim roll, a plurality of guide rollers for receiving the tapes from said reels, said guide rollers spaced from one another along the width of the scrim with their axes at right angles to the axes of the reels, and guide rods disposed parallel with the feed'rolls receiving tapes from the guide reels and delivering the tapes to the feed rolls.

2. In a bookbinding machine in combination with scrim rolls and feed rolls for feeding the scrim to the back of the books, means for delivering a plurality of relatively narrow tapes with the scrim to the feed rolls and to the backs of books in a constant but changeable position in relation to the width of the scrim from a' plurality of relatively wide tape reels affording supplies of tape, said means including a plurality of tape reels in spaced relation, said reels disposed with their axes at right angles to the axis of the scrim roll, a plurality of guide rollers for receiving the tapes from said reels, said guide rollers spaced from one another along the width of the scrim with their axes at right angles to the axes of the reels, and guide rods disposed parallel with the feed rolls receiving tapes from the guide reels and delivering the tapes to the feed rolls, said guide rollers being supported on brackets adjustably mounted on said guide rods.
